Costelytra Zealandica
''Costelytra zealandica'' (commonly known as the grass grub) is a species of scarab beetle found in forested areas of greater Wellington Greater Wellington, also known as the Wellington Region (Māori: ''Te Upoko o te Ika''), is a non-unitary region of New Zealand that occupies the southernmost part of the North Island. The region covers an area of , and has a population of T .... It was originally described in 1846 by the British entomologist Adam White as ''Rhisotrogus zealandicus'' from a specimen obtained during the Ross expedition. The species is known to feed on roots of plants and trees, so is considered a pest for many farm pastures. Prior to 2016, the New Zealand grass grub was mischaracterized as ''C. zealandica''. In 2016 Coca-Abia and Romero-Samper found differences in syntype specimens between White's (1846) ''C. zealandica'' and Given's (1952) description and revised the species name of the latter to '' Costelytra giveni'' after Given.

Auckland War Memorial Museum
The Auckland War Memorial Museum Tāmaki Paenga Hira (or simply the Auckland Museum) is one of New Zealand's most important museums and war memorials. Its collections concentrate on New Zealand history (and especially the history of the Auckland Region), natural history, and military history. The present museum building was constructed in the 1920s in the neo-classicist style, and sits on a grassed plinth (the remains of a dormant volcano) in the Auckland Domain, a large public park close to the Auckland CBD. Auckland Museum's collections and exhibits began in 1852. In 1867 Aucklanders formed a learned society – the Auckland Philosophical Society, later the Auckland Institute. Within a few years the society merged with the museum and '' Auckland Institute and Museum'' was the organisation's name until 1996. Auckland War Memorial Museum was the name of the new building opened in 1929, but since 1996 was more commonly used for the institution as well. From 1991 to 2003 the muse ...

Scarabaeidae
The family Scarabaeidae, as currently defined, consists of over 30,000 species of beetles worldwide; they are often called scarabs or scarab beetles. The classification of this family has undergone significant change in recent years. Several subfamilies have been elevated to family rank (e.g., Bolboceratidae, Geotrupidae, Glaresidae, Glaphyridae, Hybosoridae, Ochodaeidae, and Pleocomidae), and some reduced to lower ranks. The subfamilies listed in this article are in accordance with those in Bouchard (2011). Description Scarabs are stout-bodied beetles, many with bright metallic colours, measuring between . They have distinctive, clubbed antennae composed of plates called lamellae that can be compressed into a ball or fanned out like leaves to sense odours. Many species are fossorial, with legs adapted for digging. In some groups males (and sometimes females) have prominent horns on the head and/or pronotum to fight over mates or resources. The largest fossil scaraba ...

Wellington Region
Greater Wellington, also known as the Wellington Region (Māori: ''Te Upoko o te Ika''), is a non-unitary region of New Zealand that occupies the southernmost part of the North Island. The region covers an area of , and has a population of The region takes its name from Wellington, New Zealand's capital city and the region's seat. The Wellington urban area, including the cities of Wellington, Porirua, Lower Hutt, and Upper Hutt, accounts for percent of the region's population; other major urban areas include the Kapiti conurbation (Waikanae, Paraparaumu, Raumati Beach, Raumati South, and Paekākāriki) and the town of Masterton. Local government The region is administered by the Wellington Regional Council, which uses the promotional name Greater Wellington Regional Council. The council region covers the conurbation around the capital city, Wellington, and the cities of Lower Hutt, Porirua, and Upper Hutt, each of which has a rural hinterland; it extends up the west coa ...

Ross Expedition
The Ross expedition was a voyage of scientific exploration of the Antarctic in 1839 to 1843, led by James Clark Ross, with two unusually strong warships, HMS ''Erebus'' and HMS ''Terror''. It explored what is now called the Ross Sea and discovered the Ross Ice Shelf. On the expedition, Ross discovered the Transantarctic Mountains and the volcanoes Erebus and Terror, named after his ships. The young botanist Joseph Dalton Hooker made his name on the expedition. The expedition inferred the position of the South Magnetic Pole, and made substantial observations of the zoology and botany of the region, resulting in a monograph on the zoology, and a series of four detailed monographs by Hooker on the botany, collectively called ''Flora Antarctica'' and published in parts between 1843 and 1859. The expedition was the last major voyage of exploration made wholly under sail. Among the expedition's biological discoveries was the Ross seal, a species confined to the pack ice of Antarcti ...

Costelytra Giveni
''Costelytra giveni'' (mischaracterized as ''Costelytra zealandica'' prior to 2016), commonly known as New Zealand grass grub, is a scarab beetle that is endemic to New Zealand and is a prevalent pasture pest. Taxonomy ''Costelytra giveni'' was first described by B.B. Given in 1952, though he mischaracterized specimens as '' C. zealandica''. In 2016, Coca-Abia and Romero-Samper found differences in syntype specimens between White's (1846) ''C. zealandica'' and Given's (1952) description, and revised the species name of the latter to ''C. giveni'' after Given''.'' Identification/description New Zealand grass grubs are one of the most common insects in New Zealand. Grass grubs belong to the holometabolous insect group, this means that they have a life cycle with four stages: egg, larva, pupa, adult. The adult beetle can grow up to a mature length of 13 mm. It has a shiny brown colouring with a thick wing covering called an elytra. Adult beetles also have a prominent plate ...

Melolonthinae
Melolonthinae is a subfamily of the scarab beetles (family Scarabaeidae). It is a very diverse group; distributed over most of the world, it contains over 11,000 species in over 750 genera. Some authors include the scarab subfamilies Euchirinae and Pachypodinae as tribes in the Melolonthinae. Unlike some of their relatives, their habitus is usually not bizarre. They resemble the Rutelinae in being fairly plesiomorphic in outward appearance. Like in many Scarabaeidae, males have large fingered antennae, while those of the females are smaller and somewhat knobby. In the Melolonthinae, this sexual dimorphism is particularly pronounced. Many species have striking – though rarely brilliant or iridescent – hues and bold patterns of hairs. Being often quite sizeable and swarming in numbers at certain times, for example the ''Amphimallon'', ''Phyllophaga'' and ''Polyphylla'' "june beetles" or the ''Melolontha'' cockchafers – all from tribe Melolonthini – featu ...
